The Java API supports this while mostly used for tests it can also be useful in production environments. For instance if something is automated like a settings change and we execute some health right after it the settings update might have some consequences like a reroute which hasn't been fully applied since the preconditions are not fulfilled yet. For instance if not all shards started the settings update is applied but the reroute won't move currently initializing shards like in the shrink API test. Sure this could be done by waiting for green before but if the cluster moves shards due to some side-effects waiting for all events is still useful. I also took the chance to add unittests to Priority.java Closes #19419 |

Elasticsearch REST API JSON specification
This repository contains a collection of JSON files which describe the Elasticsearch HTTP API.
Their purpose is to formalize and standardize the API, to facilitate development of libraries and integrations.
Example for the "Create Index" API:
{
"indices.create": {
"documentation": "http://www.elastic.co/guide/en/elasticsearch/reference/master/indices-create-index.html",
"methods": ["PUT", "POST"],
"url": {
"path": "/{index}",
"paths": ["/{index}"],
"parts": {
"index": {
"type" : "string",
"required" : true,
"description" : "The name of the index"
}
},
"params": {
"timeout": {
"type" : "time",
"description" : "Explicit operation timeout"
}
}
},
"body": {
"description" : "The configuration for the index (`settings` and `mappings`)"
}
}
}
The specification contains:
- The name of the API (
indices.create), which usually corresponds to the client calls - Link to the documentation at http://elastic.co
- List of HTTP methods for the endpoint
- URL specification: path, parts, parameters
- Whether body is allowed for the endpoint or not and its description
The methods and url.paths elements list all possible HTTP methods and URLs for the endpoint;
it is the responsibility of the developer to use this information for a sensible API on the target platform.
